Struct MenuVTable

#[repr(C)]
pub struct MenuVTable {
    pub drop: unsafe extern "C" fn(_: VRefMut<'_, MenuVTable>),
    pub sub_menu: unsafe extern "C" fn(_: VRef<'_, MenuVTable>, _: Option<&MenuEntry>, _: &mut SharedVector<MenuEntry>),
    pub activate: unsafe extern "C" fn(_: VRef<'_, MenuVTable>, _: &MenuEntry),
}

Interface for native menu and menubar

Fields

drop: unsafe extern "C" fn(_: VRefMut<'_, MenuVTable>)

destructor

sub_menu: unsafe extern "C" fn(_: VRef<'_, MenuVTable>, _: Option<&MenuEntry>, _: &mut SharedVector<MenuEntry>)

Return the list of items for the sub menu (or the main menu of parent is None)

activate: unsafe extern "C" fn(_: VRef<'_, MenuVTable>, _: &MenuEntry)

Handler when the menu entry is activated

Implementations

impl MenuVTable

pub fn new<T: Menu>() -> Self

Create a vtable suitable for a given type implementing the trait.

Trait Implementations

impl VTableMeta for MenuVTable

type VTable = MenuVTable

That’s the VTable itself (so most likely Self)

type Target = MenuTO

That’s the trait object that implements the functions

impl VTableMetaDrop for MenuVTable

unsafe fn drop(ptr: *mut MenuTO)

Safety

fn new_box<X: HasStaticVTable<MenuVTable>>(value: X) -> VBox<MenuVTable>

allocate a new VBox
